Surf zone imaging with moored video system

在通常的冲浪区观测中，采用了固定在定点的测量装置，提供了水动力项目的准确时间记录。然而，这些仪器的部署在大多数野外实验中都是有限的，这限制了对冲浪区动力学的空间理解。在此背景下，开发了一个系泊视频系统来获取冲浪区的空间图像。现场实验是在位于日本哈崎市的研究码头HORS进行的。录像处理的结果显示了该系统的潜力，表明该系统能够捕捉到海浪带水动力的非定常和空间特征。

Measuring devices that are fixed to definite points are employed in the usual surf zone observations, which provide accurate time records of hydrodynamic items. The deployment of the instruments, however, is limited in most field experiments, which restricts the spatial understanding of the surf zone dynamics. In this context, a moored video system is developed to obtain spatial images of the surf zone. Field experiments were conducted at HORS, a research pier located in Hazaki, Japan. Results of the video record processing demonstrated the potential of the system showing that the system is able to capture the unsteady and spatial features of the surf zone hydrodynamics.
